Surgical approach and patient-reported outcomes after total hip replacement
Hip international : the journal of clinical and experimental research on hip pathology and therapy
Previous research has mainly focused on how factors such as surgical approach might affect implant survivorship and the incidence of complications. Given the increasing interest in patient-reported outcomes, the purpose of this study is to explore whether surgical approach is associated with patient-reported pain, function, and satisfaction at 1-3 years after primary total hip replacement (THR). Details of surgical factors were collated from operation notes for all consecutive patients at our centre from 2004-2006. All patients were mailed a questionnaire 1-3 years following surgery that collected WOMAC pain and function scores and the Self-Administered Patient Satisfaction Scale for Primary Hip and Knee Arthroplasty. Of the eligible 1,315 patients, 911 patients returned a completed questionnaire (69% response rate). Multivariable fractional logit models were used to identify whether surgical approach was associated with outcome scores. Surgical approach was found to be a significan...
Predictors of hip joint replacement in new attenders in primary care with hip pain
The British journal of general practice : the journal of the Royal College of General Practitioners, 2003
Studies investigating the factors associated with need for total hip replacement should ideally be based on prospective investigation of new attenders in primary care. To determine the incidence of listing for total hip replacement, and its predictors, among attenders in primary care with a new episode of hip pain. Prospective multicentre cohort study. One hundred and ninety-five patients (mean age = 63 years, 68% female) with new episode of hip pain, attending primary care between November 1994 and October 1997. At the first visit, patients were evaluated for indices of pain and disability, range of hip movement, and radiographic changes of osteoarthritis. General practitioner participants were recruited from the membership of the Primary Care Rheumatology Society to recruit all consecutive attenders with a new episode of hip pain. Annual follow-up was carried out to determine which patients were being 'put on a waiting list' for total hip replacement. Seven per cent of pat...

Objectives-To describe the practical difficulties experienced by patients when completing the Oxford hip score, and to highlight the need to reconsider aspects of its structure and conceptual base. Design-Qualitative study incorporating the Oxford hip score in semi-structured interviews with patients before and four months after their operation. Setting-Two hospitals in the North of England. Subjects-Osteoarthritic patients undergoing primary elective total hip replacement. Results-Use of the Oxford hip score provided quantitative data on disability in the sample, particularly about pain and immobility. It also facilitated the collection of qualitative data, serving as a useful starting point for interviews and as a prompt for indepth discussion. Concerns about the clarity, coverage, and content validity of the score were identified, however, raising questions about the measure's conceptual base. Conclusion-The Oxford hip score was found to be a useful precursor to the semistructured interviews. However, deficiencies in instruction and lack of clarity in purpose have implications for its ongoing development and future application, both in this type of study and other, more general, contexts.

Knee and hip osteoarthritis are highly prevalent in the older population. Management of osteoarthritis-related pain includes conservative or surgical treatment. Although knee or hip joint replacement is associated with positive outcomes, up to 30% of patients report postoperative pain in the first two years. This study aimed to synthesize current evidence on prognostic factors for predicting postoperative pain after knee or hip replacement. An umbrella review of systematic reviews was conducted to summarize the magnitude and quality of the evidence for prognostic preoperative factors predictive of postoperative chronic pain (>6 months after surgery) in patients who had received knee or hip replacement. Searches were conducted in MEDLINE, CINAHL, PubMed, PEDro, SCOPUS, Cochrane Library, and Web of Science databases from inception up to 5 August 2022 for reviews published in the English language. A narrative synthesis, a risk of bias assessment, and an evaluation of the evidence co...
Variables determining outcome in total hip replacement surgery
Journal of Bone and Joint Surgery - British Volume, 2009
In this study we hypothesised that anxiety/depression, one of five dimensions in the healthrelated quality of life (HRQoL) measurement tool EQ-5D, could predict outcome after total hip replacement surgery.
Can patient-reported outcomes predict re-operations after total hip replacement?
International orthopaedics, 2018
We investigated if patient-reported outcomes (PROMs) one year after total hip replacement (THR) can predict the risk of re-operation using data from the Swedish Hip Arthroplasty Register. A total of 75,899 patients with THR due to osteoarthritis operated in 2002-2014 were included. We used Kaplan-Meier and Cox regression to investigate the relationship between one-year post-operative PROMs and risk of re-operation (all types of further hip surgery). The predictive power of the model and post-operative PROMs were evaluated by concordance index (C). Kaplan-Meier estimates for not being re-operated at eight years was 95.5% (95%CI; 95.3-95.8). Cox regression analyses showed that all PROMs, except for EQ-VAS, were associated with re-operation. The full model had a concordance index of 0.68. Satisfaction (C = 0.65) and pain (C = 0.65) in isolation had the highest predictive power. Worse PROMs predicted higher risk of re-operation. Therefore, we believe PROMs may be helpful in identifying ...

Although generally considered successful, total hip arthroplasty (THA) can yield suboptimal results in terms of pain and function in up to one forth of patients suffering from hip osteoarthritis (OA). A thorough understanding of the determinants of patient-reported pain and function following THA can help plan interventions directed at improving surgical results. Previously published systematic reviews do not permit to confidently identify the determinants of THA outcomes because of unsatisfactory methodological designs. Therefore, we aimed to answer: (1) which preoperative factors are most consistently associated with postoperative patient-reported pain and function up to 2 years following primary unilateral THA for hip OA. Medline, Pubmed, Embase and CINAHL were screened from their respective inception dates until April 2015 using a combination of keywords and MESH terms. Criteria for inclusion were: (1) participants with primary unilateral THA for hip OA followed for at least 3 months with a maximal followup of 2 years; (2) validated disease-specific patient-reported outcome measures assessing pain and/or disability; (3) identification of determinants obtained via multivariate analyses. Methodological quality was assessed using a modified version of the methodology checklist for prognostic studies. Twenty-two manuscripts were included. Mean score of the methodological quality was 81.0 ± 10.3% (66.7% to 100%). Among socioeconomic determinants, a lower educational level was significantly related to worse pain and function (3 out of 3 studies evaluating the relationship). Clinical determinants of poor outcomes included preoperative levels of pain and physical function (9 out of 12 studies), higher body mass index (6 out of 10 studies), presence/greater level of comorbidities (7 out of 8), worse general health (4 out of 4 studies) and lower radiographic OA severity (3 out of 4 studies). Study heterogeneity limited the pooled assessment of the strength of associations between the preoperative variables and THA outcomes. Studies with moderate-to-high methodological quality allowed to identify 6 preoperative variables consistently associated with medium term pain and function following THA. This knowledge may assist the management of patients at risk of poor results. Further research is required to clarify the force of associations between determinants and THA outcomes.
